NTSB Says Straight-Truck Safety Needs More Attention

The National Transportation Safety Board says the government should consider making medium-duty straight truck drivers get a commercial driver's license, following a five-year study that found these trucks were involved in a disproportionate number of fatalities.

Other recommendations included making straight trucks subject to similar safety rules for tractor-trailers, including requirements for rear underride guards and conspicuity, as well as even tougher measures, such as side underride protection and blind spot technology.

The board's safety study on single-unit truck crashes researched the injury severity and crash characteristics of single-unit trucks over a five-year period during 2005-2009.

It defines single-unit trucks as large trucks that have a gross vehicle weight rating over 10,000 pounds with non-detachable cargo units and have all axles attached to a single frame.

“Crashes involving single-unit trucks resulted in about 1,800 deaths each year during 2005-2009 and also caused thousands of injuries,” said NTSB Chairman Deborah A. P. Hersman. “These trucks are ubiquitous in our communities, yet they are exempted from many safety rules. We must do better for our citizens.”

NTSB can only make recommendations to the DOT and its agencies. It cannot force the creation of new rules.

The Study

The study examined how the risks and characteristics of single-unit truck crashes compared with those of tractor-trailer crashes and identified areas for safety improvements. Highlights from the study include:

• Single-unit trucks were involved in a disproportionate number of passenger vehicle occupant deaths in multi-vehicle crashes.

• Single-unit truck crashes have a considerable impact on society, as measured by fatalities, injuries, hospitalizations and emergency department visits.

• Single-unit trucks should be subject to certain vehicle safety rules applicable to tractor-trailers, including requirements for rear underride guards and treatments to enhance conspicuity.

• Adverse effects of single-unit truck crashes have been underestimated in the past because these trucks are frequently misclassified and therefore undercounted in federal and state databases.

• Multiple data sources are needed to get an accurate picture of large truck safety, including two sources, Trucks in Fatal Accidents and state Crash Outcome Data Evaluation Systems, that are scheduled to be discontinued.

The Recommendations

As a result of the findings of this study, the NTSB issued safety recommendations to the National Highway Traffic Safety Administration, the Federal Motor Carrier Safety Administration, the Federal Highway Administration, and the U.S. Department of Transportation.

The safety recommendations address modifications to enhance the ability of single-unit truck drivers to detect pedestrians and cyclists, to prevent passenger vehicles from underriding the rear and sides of large trucks, and to improve visibility of single-unit trucks on dark and unlit roads.

The NTSB is also recommending improving federal and state data on large truck crashes, continuing functions now performed by Trucks in Fatal Accidents and the state Crash Outcome Data Evaluation Systems, examining the magnitude and consequences of single-unit truck drivers operating with an invalid license, and evaluating potential benefits for expanding the requirement for commercial driver’s licenses to lower truck weight classes.

The study used a variety of data sources, including state records of police and hospital reports, federal databases, and case reviews of selected single-unit truck crashes.

A synopsis of the NTSB safety study, including the findings and a complete list of the safety recommendations is available on the board’s website. The full report will be available on the NTSB website in a few weeks.

Based on over 35 years of CMV operation I can honestly say that it's about time that someone finally paid attention to the straight truck operators. Not to say that all these drivers are bad but most of them I would classify as "over grown 4 wheelers".

As a fleet manager and CDL holder for many years, it amazes me that we allow a situation where a CDL is necessary to drive a 26,000# GVWR truck while the exact same truck "derated" to 25,900# GVW can be driven by anyone with a basic license. I agree that anyone driving a vehicle over 10,000# GVWR should have a CDL.
